VLCANZER FOR CGRD TIRES.

Speeication of Letters Patent.

Patented Sept. 3, ii9d9.

Application filed october 8, 1917. Serial No. 195,389.

To all 'whom t may concer/nk' Be it known that l, EDWINA G. TEMPLETON, a citizen of the United States, 'residing at Akron, in the county of Summit andv State of Ohio, have invented new and-y useful Improvements in Vulcanizers for Cofrd Tires, of which the following is a specification.

My present invention relates to vulcanizer presses and more particularly to' the type of steam heated vulcanizer press which is employed for the vulcanizing of tires.

In acordaiice with the present practice governing the use of tire-curing vulcanizer presses, or heaters, a chain and grapple is employed to lift the heavy cover from its locked`position at the mouth of the press, in order that the cured tires within the press may be successively raised upon the ram platen to the mouth of the press for removal therefrom. When the molds aredowered into the press, the cover is lowered into place by means of a chain and grapple and locked in position over the press mouth. Inas much as this covei forms a fixed head against which allof the molds are compressed by upward movement Yof the ram platen, it will be obvious that its durable construction necessitates great weight, with a consequent awkwardness and lack 0f ease in handling.

The vulcanization of some types of tires, notably those known as cord tires,l requires relatively short curing periods and, since an discharge of any set of molds which has completed the period of vulcanization, it

will be apparent that the laborer havingchaige of the press will be forced to handle the heavy heater cover very frequently during the course of a working day.

It is the principal object of this invention, accordingly, to lighten the manual laboi' 'required in charging and discharging the tire vulcanizing press at frequent intervals, by providing means of a mechanical nature which are adapted to undertake the removal and replacement of the heater cover wit-hout the necessity of manual supervision.

It is the more specific object of the invention to provide a cover lifting and sup porting means to be carried directly by the ram .platen and in such a manner that the lif.- ing and supporting means for the cover will be inoperative thereupon when the cover is locked in position over the press mouth,

but will become automatically effective to remove the cover from the mouth of the press well when it'has-been unlocked and is free for removal.

it is a further object of the invention to provide a lifting and supporting apparatus of a similar nature, which willbe' hereinafter more specifically treated, may be accomplished by such means las are illustrated in the accompanying drawings, described in the following specification, and then more particularly pointed out iii the claims which are appended hereto and form a part of this application.

With reference to the drawings, wherein there has been illustrated' a preferred embodiment of the invention as itis reduced to practise, and throughout the several -views of which, similar reference numbers Y designate corresponding parts:

' Figure lis a View in combined side elev tron and -vertical section of an ordinary of vulcanizer press and provided with he' mechanical means of this invention; f f EigQ is a partial top plan ofthe press with the cover in unlocked position;

Fig. Sis a. detail vertical section showing the method in which the cover lifting and supporting means become operative on an unlocked cover;

Figa is a similar sectional view of the press with the .cover locked thereon, and with the liftgeand supporting means therefor, accordingly, ineffective to remove the cover; and

Fig. 5 is a diagrammatic view ofa slightly modified form of my invention.

There is illustrated iii Fig. l a press generically denoted by the number 5 of any ordinary or usual construction. The mouth of this press is provided with an annular casting or metal :Fixture 6, whose inner rim is formed with a plurality 'of female locking lugs 7 which are equidistaiitly spaced from each other and which overlie the annular locking channel 8. The cover 9 of the press Q insa fits relatively loosely Within the annular' casting 6 `and is provided with male locking members 10 ot substantially the same con-- figuration as the female lugs 7 and equi" distantly spaced in order that they may pass vertically through the spaces between the lugs 7 until reaching the interior of the locking channel 8, at which time they may be partially rotated to pass underneath the female lugs 7 and. thus maintain the cover v9 in locked position over the Well mouth.

This castellated or breech lock mechanism is of the type customarily employed for tire vulcanizers owing to its simple and edieient operation. y

itis upon 'the fact that the locking cover '9 et the press is given an angular rotational movement through a. slight angle in order to move 'from `its locked position to its unineffective to engage the covo' wlien'the latter has been" rotated from its unlocked position into its locked placen'iei'it` Through the bottom ot the press well 5 `there extends a rain plunger 11 bearing at its upper extremity a platen 12 upon Which the mold or molds 13 may be supported. The construction illustrated may be taken as typical of a hydraulic press, and to this ordinary construction there is added, by the present invention, a plurality of supporting 'Webs le? preferably three in number and each one extending laterally from the plunger ll to similarly support the cover lifting and suprmrting rods l5. riliese rods are carried Well toward the Wall of the vulcanizer press 5 in order that they may 'form the least possible obstruction to 'the insertion of molds between the pairs of adjacent rods and on to tho ram platen, or the removal of the molds therefrom. The upper extremities of the rods pass through guide sleeves 16 With which there is adapted to vertically register a boss 17 formed on the under surface ot the cover 9. This boss is preferably provided with a recess 18 in which the upper end ot the platen rods l5 may be seated when cover 9 is occupying its unlocked position with respect to the annular tasting` 6 at the well mouth, being that position which Iis illustrated in Fig. l.

lVili the parts in position oi Fig'. 1 (wherein the over is in unlocked position),

mees

it will be apparent that upward movement oi" the platen 12 will torce all three of the oever lifting rods i5 into engagement With the recesses of their respective bosses 17 on the cover and will lii't the covei1 from its engagement with the annular casting- 6 and support it thereabove duringany loading or unloading process for the press. At the conclusion of this loading or unloading ,process, retraction of the plunger l1 into a rain pot (not shown) will restore the cover 9 correctly to the position shown in this iigure, requiring but a slight rotation of the cover to engage its locking -lugs i0 with the fixed lugs 7 of the annular casting 6 at the Well mouth.

This partial rota/t: n or the @over into its locked position brings a telescoping tube stry with each lQVdireotly into vertical re, of the cover supporting rods l5. tubes i9 are set into the top of the cover in some suoli manner as is illustrated in Fig. 4 and are set j ust such. a, horizontal dis-- tance from the vertical of the bosses 17 as will permit the tubes to nieve over into registry With the reciprocating Cover lifting roos or bars i5 when the cover is looked into the Well mouth, l

Upward movement oit 'tho rain plunger ll: with the cover in its locked placement, seil to comp" f' locked cover 9, the rods 'l5 being ine'frep to the cover since they have the neler scoping movement Within the tubes 19 shown in Fig. fel. lt will be apparent that provision otn three oinr the rods l5, which will be ample to raise and support the cover 9, Will not interfere materially with the loading: oil? the molds upon the ram plunger or the unloading oli the molds therefrom.

in Fig'. I have illustrated a slightly modified forni wherein l employ our supporting rods 15 for a heavier cover" suitable for a larp r vulcaiiizing press to abcomino date molds inserted the vulcanizing describe-`- What l. olaiined is:

press previously l. A. combination with a tire vulcanizer provided with a plunger reciprocable Within the body ot the vulcanizer and a cover havingA a remota; le looking engagement over the mouth oli the vulcanizer, said cover be' ing oscilla table through slight arcs between its locked and. unl clied positions, of cover lifting and ppoi ing means carried by said plunger and iavingg a fined path of reciprocation in accordance 'with the movement of said plunger, a rod ,envag'ingl boss and a telescoping tube carried oy thel cover as an adjilnct ofthe litt' t., said boss beingA rotated into registry With said lifting and supporting means When the.
